Which criteria are used for scoring performance under silence constraints?

• A. All of the above
• B. Completion rate
• C. Safety compliance
• D. Adherence to silent rules

Answer: (A)

When scoring performance under a silence constraint, you evaluate multiple aspects of how well someone handles the task without speaking. First, completion rate looks at how much of the required work gets done within the rules—it's about finishing the task, not just trying. Second, safety compliance ensures that all actions stay within safety guidelines, even while you’re keeping quiet; you won’t sacrifice safety to show progress. Third, adherence to silent rules checks that the person truly follows the no-speech, no-noise requirement, including appropriate use of nonverbal signals and avoiding whispered communication.

Taken together, these criteria give a complete picture: you need to finish the task, stay safe, and maintain the silence. That’s why all the criteria are used in scoring.
